From the TER Review Guidelines:

#6  A phone number isn't required for posting. If the provider doesn't wish to give out her phone number, please respect her decision. Type 555-555-1212 in the phone number field instead of a real number.

I don't know if it will work to type "Email Only" in the phone number field, but that's what should show up if you use the 555 number.

To refrain from people calling at all hours of the day when we ask them not to through our webpages.. we delist our phone numbers and go strictly by email. We can not screen thru phones. we screen thru emails. I dont have a problem getting reviews posted and my phone number wasnt listed for the longest time.

I have only been posting reviews for a few weeks now, but if a provider does not list a phone number on their website, then it is because they do not want to have that privacy violated by just anyone.  All providers will give a client a phone number after they have cleared them for a visit in order that they can make contact on that day to find out where to meet, etc.  However, this number should not be displayed in the reviews.  It just does not make sense to.  I have written, "e-mail only" in reviews and have had them printed, however, a recent review where I wrote that was not printed, so maybe there is a new policy.  In any case, I will not list a number if there is no number listed on the providers site.

...the *provider's* phone number? Oh crap! I thought it was for mine.

Well, that explains the buttload of crank calls this year.
